0455 FIGURE 65. ROTOR BEARING REMOVAL 53 12. If required, remove bearing with agear pullerand accessory crutch (if available) from rotor through stud, Figure 65. 13. Clamp alternator rotor in a fixed vertical or hori- zontal position to remove or install the rotor lock nut, Figure 66. Lock nut is torqued to 130-150 ft. Ib. (176-203 Nom). FIGURE 66.EXCllER ROTOR LOCKING NUT REMOVAL.
14. If bearing, shaft, or oil seal replacement is required, hold gear case upright and tap drive pinion and shaft through gear case, Figure 67. 15. (Not Illustrated)-With vise grips, remove rotor through-stud from drive pinion shaft. FIGURE 67. REMOVING DRIVE PINION SHAFT FROM GEAR CASE ALTERNATOR ASSEMBLY 16. Remove snap ring from bearing on drive pinion shaft, Figure 68. 17. Press bearing from drive pinion shaft if bearing replacement is required, FIGURE 68. DRIVE PINION SHAFT BEARING i SNAP RING REMOVAL Use care to prevent damage to the fan Assemble alternator components in reverse order blades. Broken fan blades will throw the from disassembly using additional instructions that fan out of balance and reduce the air flow rate. follow: 1. Clean and inspect all mating surfaces. 2. Coat mating area between alternator bearing and end bell bearing hole with a thin film of Molykote or equal. 3. Install rotor-through-stud in drive pinion shaft, if it was removed. 4. Install rotor and fan assembly on adapter. Guide key ‘lot in fan Onto key in drive pinion shaft. A raised line on the fan body casting indicates the location of key slot inside. The drive shaft and key can be seen through the air outlet in the adapter. 5. If they were removed, install exciter rotor and shaft bearing. Hold fan with wooden stick and torque shaft nut against exciter rotor 130to 15Oft. Ibs. (176 to 203 Nom). 54 6. Install two stator throughstuds in adapter for aligning stator assembly over rotor during assembly. 7. Install baffle ring. 8. Install remaining two stator throughstuds in adapter. 9. Install stator and end. bell. Torque nuts on through-studs to 19 to 21 ft-lbs (26 to 28 Nom). 10. Torque down rotor-through-stud nut to 55-60 ft. Ib. (75-81 Nom). lnsta’l mounting feet and control boxl2 Connect alternator Output and control leads according to appropriate wiring diagram. 13. Replace end bell cover. 14. Replace control box cover.
